Title: Manufacture of oxide superconductive wire
Inventor: IKENO YOSHIMITSU
IPC: H01B13/00
Filed: 1987-08-04
Abstract: PURPOSE:To improve the superconductive property by forming an oxide superconductor layer, then binding plural lines of either glass rods or glass tubes to fill in a glass pipe, melting and spinning the composite, and burying the plural lines in a glass base material to make a multistranded fiber. CONSTITUTION:To an oxide superconductor layer 2 formed at the outer surface of a glass rod 1, a heat treatment is applied in the oxygen ambience or in the oxygen and a haloid gas ambience when necessary. Plural lines of such a glass rod 1 are bound and filled in a large diameter of glass pipe 3 to form a composite 4. In this case, the glass pipe 3 is formed of a material of the same quality as the glass rod 1 so as to spin the whole composite 4 evenly in the melting and spinning. Then by spinning the molten part in the longitudinal direction of the composite 4 while heating and melting one side of the composite 4 partially, a multistranded type wire material 5 is produced. In such a way, a superconductive multistranded wire with a good superconductive performance can be obtained.

Title: Power steering device
Inventor: KOMAMURA SEIJI
IPC: B62D5/06
Filed: 1981-12-03
Abstract: PURPOSE:To eliminate an imcomplete return of a spool so that the spool may be surely returned to a neutral position, by applying alternate current to the spool so that the spool vibrates at a dither frequency. CONSTITUTION:When a spool 21 does not completely return even though a solenoid 22 is deenergized, a steering signal through an OR circuit 38 becomes null so that an inverter 39 reverses this signal, and therefore, an AND circuit 37 issues a high level signal since a valve position sensor 35 also issues a unit signal, thereby an oscillating circuit 41 is energized for applying alternate current to solenoid coils 33A, 33B through an amplifier 40. As the result, the spool 21 is vibrated at a dither frequency by the solenoid coils 33A, 33B, and therefore, clogging of, for example, dust causing the imcomplete return of the spool 21 is eliminated due to the dither vibration, thereby the spool 21 is pushed back toward a neutral position under the resilient force of a spring 24, 25.

IPC: G09G3/36
Filed: 1993-07-13
Abstract: PURPOSE:To attain the drive of 2-line simultaneous selected 2-line interlaced scanning for an active matrix liquid crystal display device. CONSTITUTION:Two gate wires (e.g., n-th and (n+1th) are switched to a high level simultaneously in both ways, and a picture element drive TFT for two corresponding lines is made conductive. A video signal Vsig is sampled by a signal line 1 of each column synchronously therewith. Then the n-th gate line is set to a low level earlier and the sampled video signal Vsig is written in an n-th row of storage capacitive element Cs. Since a ground terminal of the storage capacitive element Cs is connected to an (n-1)th gate line of one preceding line latched to a low level, the video signal Vsig is written surely. Then an (n+1)th gate line is restored to a low level after lapse of a predetermined time and the sampled video signal Vsig is written in the (n+1)th storage capacitive element Cs.

Title: Sequential decoding device
Inventor: YAGI TOSHIHARU
IPC: H04L1/00
Filed: 1988-08-05
Abstract: PURPOSE:To shorten the repetitive period of the rerun of a code synchronization by reopening a decoding processing from a receiving signal written into the buffer of the receiving signal the fixed number of times before that time when the buffer overflows, it is judged that there is an error in the code synchronization and the code synchronization is rerun. CONSTITUTION:When a control circuit 34 judges that a RAM 1 overflows for the error of the code synchronization, it outputs control signals B3, B4 and B1. A counter 32 responds to the control signal B3 and resets an address signal A2 into a value smaller than an address A1. A decoding circuit 35 dislocated the phase of the code synchronization by one bit of the code symbol of a convolution code, reads a receiving signal D1 out of the address A2 of the RAM 1 by the control signal B1 and respons a decoding. Thus, the pull-in time of the code synchronization can be shortened.

Abstract: PROBLEM TO BE SOLVED: To generate the exciting electric field/magnetic flux having a uniform strength against any positions of the reading region of an ID tag by shifting the exciting current of each exciting antenna for every specified period and exciting the antennas. SOLUTION: Each ID tag has its unique number (an ID number). When the tag receives electric power through the electromagnetic coupling of a non- contact type antenna, the tag serially outputs ID data with a specific frequency. In this case, an exciting antenna 21 is constituted of three comb-line exciting antennas 21a to 21c in which the comb-line sections are overlapped to each other in a longitudinal direction, the intervals between wires are uniformly separated from each other and arranged in a comb-line shape on a detection surface. Moreover, the exciting currents I1 to I3 supplied to the antennas 21a to 21c from power supplies AV1 to AV3 are shifted for every 2π/3 period. Furthermore, it is desirable to sequentially set the relative phases of the currents I1 to I3 to +0, +2π/3 and +4π/3 in a repetitive manner.
